Understanding Unfair Competition in the Philippines: Lessons from a Landmark Supreme Court Case

The Intellectual Property Code of the Philippines protects businesses not just through trademarks and patents, but also through the law on unfair competition. This legal concept prevents one business from passing off its goods as those of another by copying their look and appearance. A 2021 Supreme Court decision, Kho v. Summerville General Merchandising & Co., Inc. (G.R. No. 213400), offers a clear and practical illustration of how this protection works, particularly when products look confusingly similar on the shelf.

The Case: Two Similar Facial Creams

Summerville General Merchandising & Co., Inc. was the exclusive distributor of a medicated facial cream bearing the trademark "Chin Chun Su." The product was sold in a distinctive pink, oval-shaped container. In 2000, Summerville discovered that Elidad and Violeta Kho, operating under the name KEC Cosmetic Laboratory, were selling their own medicated facial cream in nearly identical pink, oval-shaped containers that also bore the "Chin Chun Su" mark.

Summerville filed a criminal complaint for unfair competition against the Kho sisters. The case went through a long procedural journey involving the City Prosecutor's Office, the Department of Justice, and multiple court levels. At one point, the trial court dismissed the case for lack of probable cause, ruling that the Kho sisters had acted in good faith and had not deceived the public. The Court of Appeals reversed this decision, and the Supreme Court ultimately affirmed the appellate court's ruling.

The Legal Definition of Unfair Competition

The legal basis for the charge is found in the Intellectual Property Code of the Philippines, Republic Act No. 8293. Specifically, the Supreme Court applied Section 168.3(a) of that law, which addresses unfair competition. The provision covers any person who sells goods and gives them the general appearance of goods of another manufacturer or dealer—whether through the goods themselves, the wrapping or packaging, the devices or words thereon, or any other feature of their appearance—in a manner likely to influence purchasers to believe that the goods offered are those of another manufacturer or dealer, thereby deceiving the public and defrauding another of legitimate trade.

The Supreme Court identified two essential elements of unfair competition:

1. Confusing similarity in the general appearance of the goods; and
2. Intent to deceive the public and defraud a competitor.

Importantly, the confusing similarity does not have to come from the trademark alone. It can result from other external factors in the packaging or presentation of the goods. The intent to deceive can be inferred from the similarity of the appearance of the goods as offered for sale to the public.

What "Probable Cause" Means in This Context

A key issue in the case was whether probable cause existed to hold the Kho sisters for trial. The Supreme Court clarified that probable cause does not require absolute certainty of guilt. It is merely a reasonable belief, based on common sense, that a crime has been committed and that the accused is probably guilty. It does not require an inquiry into whether there is sufficient evidence to secure a conviction.

The Court emphasized that a judge must be cautious in dismissing a case for lack of probable cause. Dismissal is only proper when the evidence on hand "absolutely fails" to support a finding of probable cause. If probable cause exists, the judge should not hesitate to proceed with trial so that justice may be served.

Applying the Law to the Facts

Applying these principles, the Supreme Court found that probable cause clearly existed. The similarities between the two products were striking:

• Both were medicated facial creams;
• Both were contained in pink, oval-shaped containers; and
• Both bore the trademark "Chin Chun Su."

The Kho sisters argued that they indicated their own manufacturer's name on their product, which should have prevented confusion. The Court rejected this argument. An ordinary purchaser would not normally inquire about the manufacturer of a product. The act of labeling the product with a different manufacturer's name did not change the fact that its general appearance was confusingly similar to Summerville's product.

The Court also noted that while the Kho sisters may have had rights to use the oval-shaped container, they had no authority to imprint the "Chin Chun Su" mark on it. The similarities far outweighed any differences, and the element of intent to deceive could be inferred from the confusingly similar appearance alone.

The Double Jeopardy Question

The Kho sisters also raised a double jeopardy defense, arguing that the case against them had already been dismissed and could not be revived. The Supreme Court rejected this argument. Double jeopardy requires all of the following: (1) a valid indictment, (2) before a court of competent jurisdiction, (3) arraignment of the accused, (4) a valid plea, and (5) acquittal or conviction, or dismissal without the accused's express consent.

The Court noted that this issue had already been resolved in a prior resolution in G.R. No. 163741, where it was clearly pronounced that reinstatement of the Information was not barred and double jeopardy had not set in.

Practical Takeaways

• Unfair competition is broader than trademark infringement. Even if a product does not copy a registered trademark exactly, it can still be liable if its overall appearance—packaging, container shape, color, and other features—is confusingly similar to another product.
• Intent can be inferred from appearance. A business does not need to admit that it intended to deceive the public. The intent to deceive and defraud can be presumed from the confusingly similar appearance of the goods as offered for sale.
• Labeling your product with your own name is not a defense. If the overall appearance of your product is confusingly similar to a competitor's, simply putting your own manufacturer's name on it will not shield you from liability.
• Probable cause is a low threshold. For criminal charges to proceed, the evidence only needs to show a reasonable belief that a crime was committed—not proof beyond reasonable doubt. Dismissal at this stage is only proper if the evidence absolutely fails to support a finding of probable cause.
• Double jeopardy protections have limits. The right against double jeopardy only attaches after a valid indictment, arraignment, plea, and a dismissal or acquittal without the accused's consent. It does not bar the reinstatement of a case when these requisites are not fully met.
